Answer:
the floor leader
Explanation:
The speaker of the house leads the House of Representatives. The Senate has Democratic and Republican floor leaders that are elected at the beginning of each Congress. Depending on which party is in power, one serves as majority leader and one serves as minority leader. Because the Republican Party is in power right now, the majority leader would be Republican and the minority leader would be Democrat. So, the majority leader or floor leader leads the Senate.
Hope that helps.
